Patent DE-2516511-A1 (DE)
Title: Mounting arrgt. for tools - consists of board with round holes and keyhole shaped holes
Inventor: SCHMITT EMIL
IPC: B25H3/04
Filed: 1975-04-15
Abstract: A mounting board to support tools which are used e.g. during work on one particular engine, is covered by a regular pattern of holes, some of which are round and some of which are keyhole shaped. Round holes are positioned at the same pitch distance at either side of the keyhole shaped ones. Patches of self-adhesive foil stuck on the mounting board have the same outline as the tools which are to be mounted on them. Holes are punched through foil in line with the holes in the board, in those positions where they are required to support the tools.

Title: Monocoque low-slope trigonal domes for roofs - with mathematically exact minimal surfaces, assembled alternately above and below structure field
Inventor: TAEUBER WOLFRAM
IPC: E04B1/19
Filed: 1975-04-17
Abstract: System involving cable bracing held in equilibrium, can be combined with trigonal three-dimensional structural systems for mass production, the object being to provide simplified construction of geodetic domes or flat roofs (1) by means of trigonal bar lattice structure, in single-skinned layout and over wide spans. The dome or flat roof surface makes use of the static qualities of mathematically precise minimal surfaces (2), serving as external and internal skin, to take over all the tension forces of the trigonal three-dimensional structure coming together at the points of tetrahedrons (3) or similar. For this purpose they are assembled, with lever action, alternately on the upper and lower side of the single-skin trigonal structure field.

Title: Kitchen cabinet with swinging drawer - has parallelogram linkage to maintain drawer in horizontal attitude in any position
Inventor: KNEILE KARL
IPC: A47B77/10
Filed: 1975-06-03
Abstract: The drawer of the kitchen cabinet has a support plate attached to each side wall. The support plates carry pivots for two pairs of equal length links. The other ends of these links are pivoted on bolts attached to the side plates which are screwed to the inner surface of the sides of the cabinet. The bolts are so positioned that the links form the opposite sides of a parallelogram and maintain the drawer in a horizontal attitude in its upper position or when it is swung downwards into the cabinet. The spring assemblies balance the weight of the drawer and the catch holds the drawer in its swung-out position and can be released by the lever.

Title: NRZ to RZ signals conversion for synchronous TDM system - involves using D flip flop and AND gate feedback with clock
Inventor: SSMUS ULF DIPL ING
IPC: H04L25/49
Filed: 1975-07-02
Abstract: The converter, for synchronous TDM systems, converts NRZ signals into return-to-zero signals without experiencing the problems of generating two 180 deg.-shifted signals due to component tolerance scatter and temperature effects. An AND- or NAND-gate is connected by its output to the input of the D-flipflop (1). This gate has its first input connected to the output of the D-flipflop and its second input is connected to the NRZ input signal. The clock input of the D-flip flop is connected to a clock signal line (T) carrying clock signals whose frequency is twice that of the repetition rate of the NRZ signal. If an AND-gate is used it is connected to the flip flop inverting output. If a NAND- gate is used it is connected to the non-inverting output.
Patent DE-2533310-A1 (DE)
Title: IC engine starter motor pinion drive - starter relay acts as pre resistance to motor winding to prevent pinion and starter ring damage
Inventor: OBERSCHMID ANTON
IPC: F02N11/08
Filed: 1975-07-25
Abstract: Pinion engagement relay has an engagement winding which acts as a pre-resistance for the starter motor field and armature windings. The resistance is so chosen that on actuating the starter switch, the starter motor turns relatively slowly to produce just sufficient torque to turn the starter pinion, the main current switch to the starter motor remaining open. The engagement relay simultaneously pulls the pinion level against the return spring to engage the pinion with the starter ring. Should the pinion fail to mesh, the engagement thrust ring strikes the free wheel cover and prevents the main motor switch from closing until the starter pinion fully engages with the starter ring. A diode prevents a reverse current flow to the engagement relay winding from the main switch.
Patent DE-2534425-A1 (DE)
Title: Projector with relatively low rewind speed - has non-commutating motor with gearing system or interchangeable components for backward running
Inventor: LINDE VOLKER
IPC: G03B21/43
Filed: 1975-08-01
Abstract: A cine film type projector has a normal forward feed velocity but a higher rewind or backward running speed. A drive motor system is provided which is of the non-commutating or transformation type. The drive motor is connected to the projector system by means of a gearing or transmission system which provides the requisite drive velocity for the projector. The gearing system consists of a series of easily interchangeable gear cogs and wheels. This gives a rewind or backward drive approx. one and a half times greater than the forward speed. This prevents damage to the film.

Title: Code converter with device generating pulse train - operates when specified signals appear in binary signal train to be converted
Inventor: YAMASHITA KIICHI
IPC: H04L25/49
Filed: 1975-09-12
Abstract: Binary signal train and clock pulses are applied to the code converter gate (203); and there is a delay line (204), which is connected to the code converter gate whose time delay is approx. half the pulse width; an adder (205) adds the delay line output signals to clock pulses, and a frequency divider (206), connected to the adder, divides the output frequency of the latter, so that the binary signal train is converted into transmission signals in a different code. The signal train is applied to a first terminal (201) which is connected only to the gate (203). The clock pulses are applied to the second terminal (202) which is connected to the gate and is also connected directly to the adder (205).

Patent DE-2614019-A1 (DE)
Title: Keyboard dialling telephone circuit - generates defined output potentials and uses bistable relay whose contact closes capacitor charging circuit on diode blocking
Inventor: TETZLAFF HARTMUT ING GRAD
IPC: H04M1/31
Filed: 1976-04-01
Abstract: When the star selection switch is operated and the relay selection contact moves into dialling position, a capacitor is charged when a first four-layer diode blocks a low-ohmic parallel circuit. The capacitor energy then feeds the relay coil via a second four-layer diode and another diode. The second four-layer diode is ignited by the transmitted capacitor energy. The relay coil feed brings the relay contact into its call connecting position. Alternately, on connection to exchange, the relay contact moves into dialling position causes a voltage drop at a zener diode, conditioned by a transistor delay. The voltage drop generates a pulse actuating the relay energisation via a further diode.

Title: Screw joint for conducting cables - has axial nut bending clamping strips inward when tightened to compress seal against conductor surface
Inventor: HOLZMANN HERMANN
IPC: H02G3/06
